Which of the following Belgian beers is always made with wheat?

Witbier is a style of Belgian beer that is characteristically brewed with a significant proportion of wheat, typically comprising around 30% or more of the grain bill. This use of wheat is fundamental to the style, contributing not only to its hazy appearance but also to its light, refreshing mouthfeel and its ability to hold carbonation. Additionally, Witbiers are often spiced with coriander and orange peel, enhancing their flavor profile and making them distinctively aromatic.

In contrast, the other styles mentioned, such as Dubbel, Tripel, and Quadrupel, are primarily made with barley malt and can include other grains, but they do not have the wheat base that is essential to Witbier. These styles focus on malt richness and complexity rather than the wheat-derived qualities that define Witbier. Thus, recognizing that Witbier is the only one always made with wheat aligns well with the characteristics of these beer styles.
